IMPROVED METHOD 0F REGULATING WINDVIILLS.v

Specification forming part of Letters Patent No. 14,918, dated May 20, i856.

T0 all whom it may concern.'

Be it known that I, MORGAN S. JOHNSON, of the town of Palatine, in the county of Cook and State of Illinois, have invented a new and Improved Vind-Power; and I hereby do declare that the following is a full and exact description.

The nature of my invention consists in providing an outside framework having a regular octagonal perimeter, (marked G in the accompanying drawings,) With doors (marked H) attached to circle A by means of bar B, and also attached to the perimeter G by means ot' hinges I. Said doors are'made to open and shut by turning the shaft C, on which shaft is pinion E. The said pinion E meshes into segment F, which segment F is attached to circle A, thus letting in Or shutting out wind at pleasure. Circle A is held to its place by means of friction-rollers J, also for the fastening on the upper part ot the doors, as shown at letter D, the object of which is the better securing of said doors in high Winds; also the position of the wings of the cylinder inside of the frame-work, as shown at tigure 2 in the drawings, in reference to their capacity for readily receiving and discharging the Wind.

The advantages ot my invention over any and all other wind-powers that I have seen or heard of are that, While they are unprotected from storms and are liable to be blown down in gaies, mine is safely housed and secured from damage. However strong may be the Wind, no more need be let into my machine than is Wanted. I also claim that my machine is free from back Winds. I consider it safe and good as a motive power for propelling grist-mills, saw-mills, for raising water, and for all kinds of machinery Where wind can be used. It is so constructed thatit matters not which way the wind blows the Wheel is always in a proper position to receive the full power of the wind.

I claim- The particular mechanical devices as arranged for the purpose of housing the sails, as and for the purposes set forth.

MORGAN S. JOHNSON.
